Why is this a Guide Pick?

Solveig Waterfall

A product with both a durable nylon bottom and a leak-proof valve that is easy to operate while wearing gloves is critical to restful sleep while logging nearly a month of cold glacial nights. This mat is worth it's weight in Alaskan gold, and yet it's still light enough to almost forget it's there...if there wasn't 75 pounds of other gear in my pack as a reminder!
